How do I formate spaces in terminal for FFMPEG metadata
22 juillet 2020, par pbendevisI can't get FFMPEG to accept any spaces when I try to assign it to the metadata. Below is the command I am using in Terminal on MacOS. It gives me an error :
[NULL @ 0x7fce76026600] Unable to find a suitable output format for 'World' World: Invalid argument

I have tried
'title="Trolls World Tour"'
title=Trolls" "World" "Tour
to no luck.

Using
title="Trolls\ World\ Tour"
works but then the title includes the backslashes.

Any thoughts ?

How to put video on top of overlay using FFmpeg ?
23 juillet 2020, par user3058763How to merge a video and an image (or a black overlay) to get the video on top ?


Input video is already prepared for this (its maximum width/height is 1920x1080) and needs to stay at original size.


This is how it should look like :



orange is an overlay/image (1920x1080px),
pink is a video on top of it (and centered)


The best shot so far I've got :


ffplay -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" input.mp4



this most likely works, but I can't save the image to check.


But this does nothing to the video :


ffmpeg -i input.mp4 -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4



Bonus points if you know how to put an image instead of black overlay.
Thank you !


Full logs of the command (output video remains the same resolution as input) :


ffmpeg -i input.mp4 -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4

ffmpeg : Extract unknown data stream from video container
23 juillet 2020, par PikkostackI have a .MOV container which contains the following tracks :


Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 100619 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)
Metadata:
 creation_time : 2020-07-21T22:48:24.000000Z
 handler_name : DJI.AVC
 encoder : AVC encoder
Stream #0:1(eng): Data: none (priv / 0x76697270), 87 kb/s
Metadata:
 creation_time : 2020-07-21T22:48:24.000000Z
 handler_name : DJI.Meta
Stream #0:2(eng): Subtitle: mov_text (text / 0x74786574), 2 kb/s (default)
Metadata:
 creation_time : 2020-07-21T22:48:24.000000Z
 handler_name : DJI.Subtitle



As you can see, stream #0:1, called DJI.meta, is of an unknown data format. I just want to extract the raw data of this stream to a file. So that is the ffmpeg command I tried :


ffmpeg -i .\DJI_0001.MOV -map 0:1 metadata



But using this command results in the following error :


Unable to find a suitable output format for 'metadata'
metadata: Invalid argument



How can I tell ffmpeg that the data should not be formated, so that only the raw data is extracted ?
